[ODUNEWS] August 15 – Great Britain has become the first country to approve a COVID-19 vaccine that targets both the original and Omicron variant of the virus.
The U.K. medicines regulator approved the so-called bivalent vaccine made by U.S. drug company Moderna as a booster for adults.
The agency’s decision was based on clinical trial data that showed the booster triggered “a strong immune response” against both Omicron (BA.1) and the original 2020 virus, it said.
The Medicines and Healthcare products Regulatory Agency (MHRA) also cited an exploratory analysis in which the shot was found to generate a good immune response against the currently dominant Omicron offshoots BA.4 and BA.5.
No serious safety concerns were identified with this new formulation, the agency added.
Now, approval has been secured, Britain’s Joint Committee on Vaccination and Immunisation (JCVI) will advise on how the vaccine should be deployed in the country.
While existing COVID-19 vaccines continue to provide good protection against hospitalization and death, vaccine effectiveness has taken a hit as the virus has evolved.
“The first generation of COVID-19 vaccines being used in the UK continues to provide important protection against the disease and save lives,” MHRA Chief Executive June Raine said in a statement.
“What this bivalent vaccine gives us is a sharpened tool in our armoury to help protect us against this disease as the virus continues to evolve.”
